This paper constructs a dynamic model of health insurance to evaluate the short- and long run effects of policies that prevent firms from conditioning wages on health conditions of their workers, and that prevent health insurance companies from charging individuals with adverse health conditions...

We analyze efficient risk-sharing arrangements when coalitions may deviate. Coalitions form to insure against idiosyncratic income risk. Self-enforcing contracts for both the original coalition and any deviating coalition rely on a belief in future cooperation which we term "social capital". We...

This paper studies the optimal design of social insurance programs for disabled workers by developing and estimating an equilibrium labor search model with screening contracts. In the model, firms may strategically use employment contracts, consisting of wage and job amenities, to screen out the...

How does investors' information about a country's fundamentals, and the fact that this information may be asymmetrically held, affect a country's financing cost? Motivated by this question, and by the observation that sovereign bonds are usually auctioned in large lots to a large number of...

A traditional explanation for why sovereign governments repay debts is that they want to keep good reputations so they can easily borrow more. Bulow and Rogoff show that this argument is invalid under two conditions: (i) there is a single debt relationship, and (ii) regardless of their past...

This paper develops the first dynamic, stochastic, general equilibrium analysis of the International Great Depression. We construct a new version of Lucas?s (1972) monetary misperceptions model, with a real shock (productivity) and a nominal shock (money supply). We use the model with a newly...

With some models of money and a representative-agent there is no reason for monetary trade because identical individuals can consume their own production. Lucas proposed a parable involving differentiated products in a cash-in-advance model to avoid this problem. This paper studies Lucas?s...

Marcet and Marimon (1994, revised 1998, revised 2011) developed a recursive saddle point method which can be used to solve dynamic contracting problems that include participation, enforcement and incentive constraints. Their method uses a recursive multiplier to capture implicit prior promises...

Our paper examines whether the well-documented failure of unsophisticated investors to rebalance their portfolios can help to explain the enormous counter-cyclical volatility of aggregate risk compensation in financial markets. To answer this question, we set up a model in which CRRA-utility...

This study exploits panel data from 18 countries to assess the contributions of cartelization policies, monetary shocks, and productivity shocks on macroeconomic activity during the Great Depression. To construct a parsimonious and common model framework, we use the fact that many cartel...
